Abstract
Abstract A pair of wedges are disposed in spaces appropriately provided between a pair of intersecting members in such a way that as the wedges are driven home sufficient forces are developed between the intersecting members to secure same to each other, but in such a manner that the application of sufficient force to one or both of said intersecting members, or to the wedges themselves, will release the wedges and permit separation of the intersecting members.

Claim 5
Dependent Claim
32 words
The equipment of claim 2: wherein each of said vertical posts is formed of a regular configuration and so that said notch extends downward from the top and across the width thereof.
Claim 6
Dependent Claim
11 words
The equipment of claim 3 wherein each said post is tubular.
Claim 7
Dependent Claim
14 words
The equipment of claim 4 wherein each said post is of circular cross section.
Claim 8
Dependent Claim
33 words
The equipment of claim 5 wherein said notch formed in said post is sufficient to provide a space to either side of said support bar and wedging means are disposed in each space.
Claim 9
Dependent Claim
36 words
The equipment of claim 6 wherein each wedging means is tapered on the face thereof disposed proximate said support bar and has its opposite surface conforming to that of the inner surface of said vertical post.
Claim 10
Dependent Claim
51 words
The equipment of claim 7 wherein said wedging means are inserted with sufficient force to develop clamping wedging forces between said support bar and vertical post to retain same interconnected throughout normal use of the equipment but so as to permit removal thereof to separate said support bar from said post.
Claim 11
Dependent Claim
11 words
The equipment of claim 8 wherein said deck comprises wire cloth.
